USING THE INVERTER
It is important to know the continuous
wattage of the device you plan to use with
the inverter. The Portable Power 1150
must be used with devices drawing 400
watts or less. If the wattage is not marked
on the device, an estimate can be made
by multiplying the AC input current (Amps)
by the AC voltage (110V).
Devices like TVs, fans or electric motors
require additional power to start (com­
monly known as the “starting or peak
power”). The Portable Power 1150 can
supply a momentary surge in wattage;
however even devices rated less than
the maximum 400 watts can exceed the
inverters surge capability and cause an
automatic overload shutdown.
Make sure the device you are using is
compatible with a modified sine wave
inverter.
CAUTION: Always run a test to establish
whether the inverter will operate a particu­
lar piece of equipment or device.
NOTE: In the event of a power overload,
the inverter is designed to automatically
shut down. This safety feature prevents
damaging the inverter while testing de­
vices and equipment with the 400-watt
range.
NOTE: When powering two-AC acces­
sories, the combined watts should not
exceed 400 watts.
POWERING A 110V AC DEVICE
To operate a 110V AC device:
1. Open the protective cover of the AC
power outlet on the front panel of the
Portable Power 1150.
2. Plug the 110V AC device into the AC
power outlet, and push the inverter
switch to ON.
3. Turn on the 110V AC device (if
required).
4. If a device will not operate properly
when first connected to the inverter,
push the inverter rocker switch ON
(I), OFF (0), and ON (I) again in quick
succession. If this procedure is not
successful, it is likely that the 1150
inverter does not have the required
capacity to operate the device in
question.
5. Charge the Portable Power 1150 as
soon as possible after each use.
CAUTION: Incorrect operation of your in­
verter may result in damage and personal
injury. Electrical current on a 120-volt
circuit can be very dangerous.
TROUBLESHOOTING:
The digital display will flash
E r r
and the
inverter will automatically turn itself off
when:
1. The input voltage from the battery
drops to approximately 10.5 volts.
(When the power input drops to ap­
proximately 11 volts an alarm will
sound for an extended period).
2. The continuous load demand from the
equipment or device being operated
exceeds 400 watts.
3. The 1150 inverter temperature ex­
ceeds 145° F.
NOTE: The 1150 is fitted with a cooling fan
that runs continuously for loads drawing
25 watts or higher. If the cooling fan is
unable to maintain a cool enough tem­
perature for safe operation, the inverter
will automatically shut down. If the inverter
automatically shuts down or a continuous
audible alarm is heard:
1. Push the inverter/compressor switch
to the OFF position.
2. Determine the source of the problem,
and resolve it before reusing the in­
verter.
